CAR STARTER AND BRAKE;

SPECIFICATION forming part of Letters Patent No. 363,770, dated May 24, 1887.

Application filed Marel1`23,l887. Serial No. 232,160. (No model.)

.To @ZZ whom it may concern:

Be it known that l, WILLIAM HENRY SNI` DER, of the city of Toronto, in the county of York and Province of Ontario, Canada, have invented certain new and useful lmp rovements in .Apparatus for Braking and Starting Cars; and I do hereby declare that the following isa full, clear, and exact description of the same.

This invention relates to appliances used for stopping and starting street-cars and vehicles of like description, and has for its object to effect the double operation of braking or stopping the car and starting s ame again by siInple and inexpensive means, which can be act-ir ated from either end of the car, and which will operate equally Well with the car ruiming in either direction.

To this end the apparatus consists, principally, in two shafts carried by a light swinging frame arranged underneath the car, said shafts being parallel to theaxles and each car` ryinga pulley and two friction-wheels,the pulley being adapted to wind np a chain 01 cord the other end of which isv secured to a spring fastened to the car-body, and the friction-pulleys arranged near the peripheries of the earwheels, so as to be readily thrown into contact therewith. Ahorizontal shaftis journaled in the swinging frame, and has miter-gears on each end, which intermesh with other mitergears mounted upon the transverse shafts, to insure the simultaneous revolution of both shafts in opposite directions, and hand-levers are also provided at each end of the car to move the swinging frame, and thus throw the friction wheels into contact with the earwheels at either end.

For full comprehension of my invention refA erenee mush be had to the accompanying drawings, forming part of this specification,in which similar letters of reference indicate like parts.

In saiddrawings, Figure l represents a bottom plan of part of a car, showing two axles and their wheels with my apparatus combined therewith; and Fig. 2aside elevation,partly in section, ofthe same devices, both ofthese views showing the car as traveling in the direction of the arrows and with the brakes applied to the rear wheels. Fig. 3 is an end elevation.

A represents the body of the ear, B B the two axles, and GO C C their respective wheels,

said axles and wheels being journaled and arranged in relation to the carin any of the wellknown ways, eitherwith or without trucks.

.D is the frame which carries the stopping and starting mechanism, preferably made up of two longitudinal and two cross bars, and hung loosely to any convenient part of the carbody, journal-bearings, or trucks by pivoted links d d.

E E are the transverse shafts, arranged parallel to the axles B B and journaled at d din the -longitudinal bars of the frame D, small collarse' e', or other equivalent means, being provided to keep said shafts from sliding lengthwise. Upon the extreme outer ends of these shafts are firmly mounted friction wheels or disks F F F F', of any suitable size, material, or -eonstruction, arranged in line with the car-wheels; also, fixed upon the shafts are pulleys or drums G G', to which are connected cords or` chains gg', the other ends of such cords being attached to coiled springs H H', which are in turn fixed at one end to the car-body A.

Centrally in the swinging frame D, and jour4 naled at 7c 7c in the cross-bars thereof, is a horizontal shaft, K, having fixed upon its ends the mitergears k' 7l?, that marked k' intermeshing with a niitergear, Lmounted on the transverse shaft E, and the gear k2 meshing with a beveled gear, L', at the side of the drum or p nlley G. The position of these gears may be reversed, or they may be otherwise modified, according to the judgment of the mechanic.

M and N are hand-levers projecting through i,

theoor of the car or its platforms, the same being iixed to the shafts E E', so as to move with them, and pivoted at their lower ends to short fixed bars m n, projecting from the journal-bearings of the car-wheels, as shown, or from some convenient parts of the trucks or car-frames.

The operation ofmy invention is as follows:

IOO

drawings, the hand-lever N has been pushed forward by the driver, and by the movement in that direction of the frame D thefrictionwheels F F thrown against the rear wheels. The rotation of the latter, acting by friction upon the disks,has caused the shafts E and E (connected as they are by the gear-shaft K) to revolve simultaneously, and in this manner wind up the cords g g upon their respective drums and extend the coiled springs H H. This being accomplished, the car is stopped. To again start the car, the lever N is released and pulled back and the tension of the springs will cause the cords to rapidly unwind from the drums, the weight of the frame assisting it to assume the reverse position, which will throw oft' the brake at the rear and apply the front friction-disks to the front wheels, and as the cord continues to unwind the friction of said front disks upon the car-wheels will cause the latter to turn,and thus start the car forward.

VWhen the springs are out of tension, the shafts E E will cease to revolve, and the handlevers being fully released, the swinging frame assumes its normal position, while the car proceeds.

Should the conductor at the rear of the car wish to apply the brake at that end, he pulls backward the lever M into the position shown, and the action above described takes place; and if the driver wishes to brake the front wheels of the car hc pulls the lever N backward, and so on.

Ratchets or clutch devices may be provided for the levers, and brakewheels or crank-shafts may be substituted for the levers shown in the drawings; and, furthermore, I may provide boxes or casings for the springs, gears, Ste., and otherwise modify and amplify the details of construction without departing from my invention.

Vhat I claim, and desire to secure by Letters Patent, is as follows:

In an apparatus for braking and starting cars, the combination, with the car-body and the wheels, of aswinging frame pivoted to the under side of the car-body, two transverse shafts, and alongitudinal shaft geared to said transverse shafts, all journaled in said swinging frame, friction wheels or disks fixed on the ends of said transverse shafts and adapted t0 be thrown into contact with the car-wheels, pulleys or drums upon the transverse shafts, springs attached to the car and connected with said pulleys or drums by cords or chains, and leversfor moving the swinging frame, all arranged to operate substantially in the manner and for the purpose sct forth.
